Plastic bags became almost a national symbol of waste and decadence thanks to BBC camerawoman Rebecca Hosking, who travelled to the remote Pacific island of Midway to film a nature documentary.

As the Guardian reported at the time: "Instead of finding some prelapsarian wilderness, she and a colleague were confronted with the horror of hundreds of albatrosses lying on the sand. The great birds' stomachs had been split open by the heat and bits of plastic were spewing out between the feathers and the bones. All kinds of plastic – toys, shopping bags, asthma inhalers, pens, cigarette lighters, toothbrushes, combs, bottle tops. The birds had swallowed them and choked to death."

Later, Hosking and her colleagues found humpback whales, seals and turtles, "all dead or dying from the plastic", which rolled in on every tide.

Hosking came back to the UK, finished the film, and returned to her home town of Modbury in Devon, where she set about persuading all 43 shopkeepers to stop using plastic bags.

Modbury's example inspired communities across the country to attempt the same thing, and led to a national debate about whether all shoppers in the UK should pay a levy to deter plastic bag use.

By the time Modbury became a national name, the Bangladeshi capital Dhaka, South Africa, Zanzibar and at least one state in India (Karnataka) had already banned distribution of single-use plastic bags, while the environment minister of Rwanda suggested using such bags was breaking environmental protection laws.

Meanwhile, Ireland introduced a levy of 15 euro cents (now 22c) a bag, slashing plastic bag use from 328 bags per person a year to just 18 last year – and cutting plastic bags from 5% of litter to a quarter of 1%.

Since then Kenya, Uganda, several more Indian states and China have introduced bans, while many European retailers charge for bags.

As with so many environmental "improvements", however, banning and charging for plastic bags has not been without controversy: earlier this year an unpublished report by the Environment Agency was leaked, showing that popular alternatives to plastic bags needed to be used many times over to generate less carbon pollution: paper bags at least four times, and cotton bags more than 171 times over.
